Even though cats that are obese need fewer fats and calories, still protein, vitamins and minerals are needed to maintain a good health. The ideal reduction formula is designed to provide all of these essential nutrients while restricting caloric intake. Protein, carbohydrates and fats are the primary source of calorie so that amount of these ingredients must be controlled carefully. Because of the restricted amounts of certain ingredients, weight loss formulas are not appropriate diets for cats of all life stages. Many experts in diet program reduced the energy value of their weight reduction food simple cannot meet the extra need of the growing kittens, pregnant cat or nursing queens, for example. Nor are weight loss foods necessarily suitable as daily rations for non breeding adult cats that do not have a weight problem, or for cats that have other medical problems. For these reasons, many pet food manufacturers design their weight loss products as therapeutic diets to be dispensed through veterinarians. This way, the veterinarian can evaluate the need for the special diet and properly monitor and supervise the cat’s weight loss progress.
Therapeutic weight reduction cat foods are usually formulated to be relatively low in calories and fat, but contain a higher fiber on it. Because fiber is poorly digestible, it delivers fewer calories relatively reducing the total stock of calories in cat’s body. The increased amount of dietary crude fiber in these formulas may also help promote a feeling of fullness in the cat so that it doesn’t feel deprived and hungry while on the weight loss diet program. However the problem with more fiber us that it produces greater stool volume that sometimes become a predisposing factor in cats constipation problems, so it is also best that when a cat in under the weight loss program, an extra amount of fluid is given.
